Comparative Study on Azo dye-doped Polymer Films for Optical Phase Conjugation
Journal Title: International Journal of Science and Research (IJSR) - Year 2015, Vol 4, Issue 4
Abstract
In this paper, we have studied the linear optical properties and nonlinear optical Phase Conjugation properties of two azo dye-doped polymer films by considering organic dyes disperse orange (DO-25) and disperse yellow (DY-7) doped in a polymer matrix Polymethyl methacrylate methacrylic acid (PMMA-MA). The nonlinear optical phase conjugation properties are studied using Degenerate Four Wave Mixing set-up using 532 nm wavelength CW laser beam. The effect of dye concentration, intensity of backward, forward pump, and inter beam angle between probe and forward pump beam on phase conjugation reflectivity are also studied and compared.
Separable Reversible Data Hiding In Image Using a Keyless Approach
Reversible data hiding is a process in which the original cover can be losslessly recovered after embedded data is extracted while protecting the image content’s confidentiality. Earlier many research papers proposed rev...
Performance Evaluation of Star Topology in Fiber Optic Communication
Topology refers to the layout of connected devices in a network. It describes the way in which the elements of the network are mapped. Optical network topologies such as bus, star and tree reduce complexity by using mini...
